Hi Ozzy,
You should take these questions over to the DIYAudio forum where there are lots of speaker builders who would help you, or Parts Express Tech Talk. Plus you can post pics and schematics and stuff there too so it's easier to share your problems and questions about speaker buiding. :)
As for power required for a resistor, I use XSim’s power charts.
It is also important to know where your resistor is going! :) Since power in music is weighted towards bass, your tweeter will never have the full music power. I assume only about 1/10 of the music power will ever go to the tweeter section. I then set XSim to that level of power, and then examine the resistors.
If in doubt, go bigger! :) Plus, bigger resistors have less thermal noise and are more stable.
